Frequently asked questions

  • Are they easy to apply?

    Yes. Each treatment contains two lightweight strips individually shaped to fit differing top and bottom teeth profiles to ensure a perfect fit and comfort in use. The wrap over design secures the strip in place and makes application easy and they only need to be applied once a day.

  • I’ve tried other strips that didn’t work. Why are these better?

    Unlike traditional acrylic strips the Wisdom design uses the patented Hydrogel delivery system that works in 3 ways for a superior whitening effect. Lightweight, hydrogel structure allows for an increased loading of whitening ingredients, whilst also ensuring the ingredients stay effective for the full 30 minute treatment. The patented material provides a strong bond with teeth during use to ensure consistent contact between the whitening ingredient and the tooth surfaces. The lightweight, malleable strip contours easily to your teeth to allow superior whitening even on uneven surfaces, including gaps and the edges of your teeth.

  • How long do they need to be used for?

    The unique Hydrogel system means the strips work fast. Use for just 30 mins, once a day for only 7 days.

  • Are they safe to use?

    Yes. As well as being clinically tested for performance they are also independently tested for product safety and comply with all European safety regulations for cosmetic products.

  • Do they contain Peroxide?

    No, Wisdom Intense White teeth whitening strips are peroxide free and safe for use on enamel.

  • Will they make my teeth sensitive?

    Wisdom Intense White strips are not known to cause sensitivity. Peroxide based whitening treatments can cause issues with sensitivity but Wisdom Intense White strips are peroxide free.

  • How often should I use the strips?

    For best results the strips should be used as directed and used once per day for the full 7 days.

  • How long will the whitening effect last?

    Using Wisdom Intense White teeth whitening strips is not a replacement for a good oral care regime. Brushing for 2 minutes, twice a day, with whitening toothpaste and also cleaning between teeth to reach all tooth surfaces, will keep your new whiter smile at its best for longer. If you smoke or eat/drink staining foods regularly or you just want to boost your smile then the treatment can be repeated as required.

  • Can I use the whitening strips on veneers, crowns or implants?

The strips will clean all your teeth but will only get the non-natural materials back to their original colour.
